What were the arguments Hawking considered naive against imaginary time?

What is Stephen Hawking’s imaginary time?

Stephen Hawking popularized the concept of imaginary time in his book The Universe in a Nutshell. “One might think this means that imaginary numbers are just a mathematical game having nothing to do with the real world. From the viewpoint of positivist philosophy, however, one cannot determine what is real.

What does imaginary time look like?


It's called imaginary time because it's directly related to the imaginary. Number i which is defined to be the square root of negative.

What is imaginary time simplified?

Simply put, imaginary time is a mathematical simplification of time used in several equations across quantum mechanics and general relativity. Think of real-time as a horizontal line. A single point on that line is a moment in time. To the left of that point is the past and to the right is the future.

What does an imaginary time block do?

The Imaginary Time Block is a block added by the QuantumFlux mod. It works by increasing the tick speed of an area, the range of which is determined by the config file. The block’s intended use is in speeding up the growth of crops, but it can be used on any block that uses the random-tick mechanism.

Why does Wick rotate?

Wick rotation is called a rotation because when we represent complex numbers as a plane, the multiplication of a complex number by i is equivalent to rotating the vector representing that number by an angle of π/2 about the origin.

What is imaginary space?

Abstract. “Imaginary space” is a three-dimensional visual awareness that feels different from what you experience when you open your eyes in broad daylight. Imaginary spaces are experienced when you look “into” (as distinct from “at”) a picture for instance.

What is Euclidean time?

Euclidean time is obtained from Lorentzian time by a Wick rotation in the complex t plane, and enters into the resulting equations exactly in the same way as a spatial coordinate x.

Is spacetime a Euclidean?

The geometry of Minkowski spacetime is pseudo-Euclidean, thanks to the time component term being negative in the expression for the four dimensional interval. This fact renders spacetime geometry unintuitive and extremely difficult to visualize.

What means Euclidean?

Definition of euclidean



: of, relating to, or based on the geometry of Euclid or a geometry with similar axioms.

How do you find the distance between two vectors in Python?

Calculate Euclidean Distance in Python

  1. Use the NumPy Module to Find the Euclidean Distance Between Two Points.
  2. Use the distance.euclidean() Function to Find the Euclidean Distance Between Two Points.
  3. Use the math.dist() Function to Find the Euclidean Distance Between Two Points.


Which algorithm is used to find GCD of two integers?

The Euclidean Algorithm

The Euclidean Algorithm is a technique for quickly finding the GCD of two integers.

Who discovered hyperbolic geometry?

The two mathematicians were Euginio Beltrami and Felix Klein and together they developed the first complete model of hyperbolic geometry. This description is now what we know as hyperbolic geometry (Taimina). In Hyperbolic Geometry, the first four postulates are the same as Euclids geometry.

How do you make a non-Euclidean in Minecraft?

First i'm going through the video settings you should use to make the portals mostly invisible in my minecraft version i have sodium installed so this looks a bit different.

Did Gauss steal?

The Bolyais believed Gauss was trying to steal the discovery, which he wasn’t; he had no intention of publishing. János Bolyai received full credit for his discovery as did Nikolai Lobachevsky who discovered it independently.
